==Mongo Db installation in Artix linux
MongoDB has been removed from the official repositories (Arch Linux) due to its re-licensing issues.
PKGBUILDs are provided in AUR: {mongodb-bin}^aur
[prahlad@artix ~]$ git clone https://aur.archlinux.org/mongodb-bin.git
[prahlad@artix ~]$ cd mongodb-bin
[prahlad@artix ~]$ makepkg -si
sudo rm /var/lib/mongodb/mongod.lock
sudo mongod --dbpath /var/lib/mongodb/ --repair
sudo mongod --dbpath /var/lib/mongodb/ --journal
(Make sure that you leave you terminal running in which you have run above lines, dont press 'Ctrl+c' or quit it.) Type the command to start mongo now in another window.
